UNITE STS PATT JOHN C. ROSS, OF AKRON, OHIO, ASSIGNOB TO THE OHIO GREASE LUBRICANT COMPANY, OF LOUDONVILLE, OHIO, A CORPORATION OF OHIO.

GREASE-LUBRIGATOR.

To all whom it may concern:

Be it known that I, JOHN C. Ross, a citizen of the United States, residing at Akron,

in the county of Summit and State of Ohio,

such a lubricator as will heat and feed.

grease, as well as normally liquid oil, into the supply line or the cylinders under all.

conditions of temperature, and also in the heated and atomized condition necessary for saturating the steam.

In lubricators designed for feeding grease into a supply line or cylinders at a considerable distance from the reservoir of the lubricator, diiiiculty is experienced in supplying the lubricant at the point of use in the heated and atomized condition necessary for properly saturating the steam; which difiiculty tends to prevent the use of a single reservoir to supply the lubricant at a plurality of places more or less remote from the reservoir, especially when it is desired to employ grease as the lubricant. These difficulties are avoided, and other beneficial results are attained, by the construction and arrangement illustrated, for a preferred embodiment of the invention, in the accompanying drawing, forming part hereof, in which Figure 1 is a vertical section of the improved lubricator; Fig. 2, a plan section of the bottom of the reservoir, on line 22, Fig. l; and Fig. 3, a vertical section showing the distributing drum, on line 3-3, Fig. 1.

Similar numerals refer to similar parts throughout the drawing.

The case 1 of the reservoir 2 is preferably made cylindric in form with the Vertical partition 3 forming the condensation-water chamber 4 on one side, the vertical partition 5 forming the sight feed chamber 6 in the other side of the reservoir, and the transverse heating pipe 7 is formed as by the arched partition 8 in the bottom of the reservoir.

The water chamber 4 is preferably extended upward as 45 by means of the pipe 3 on the upper end of which is formed or secured the case 9 forming the condensing Specification of Letters Patent.

chamber 10; the upper end of which condensing chamber is connected with the sup ply line 11 above the lubricator, by means of the steam pipe 12 which is preferably controlled by means of the valve 13. The steam pipe 14; extends upward from the heating pipe 7, preferably through the water chamber ke to an upper end opening at 15 in the upper portion of the condensing chamber; and the overflow pipe 16 leads from the side of the condensing chamber, at a point below the upper end of the steam pipe therein, into the feed pipe 17 which extends laterally from the lower end of the feed chamber 6, into the supply line; the overflow pipe being preferably controlled by a valve as 18.

The feed nipple 19 is formed or secured in the upper end of the feed chamber, and

the feed aperture 20 thereof constitutes a seat for the feed valve 21, which is preferably in the form of a needle valve; and the feed port 22 communicates from the upper end of the reservoir to the feed aperture. The water port 23 is provided in the lower end of the water chamber partition, which aperture is opened and closed by means of the condensation-water valve 24. The cross partition 25 is provided in the heating pipe 7, adjacent to the lower end of the feed chamher, and the discharge nipple 26 is formed or secured in this partition, which nipple is directed across the lower end of the feed chamber into and along the feed pipe 17.

The parts thus far described constitute a complete lubricator for feeding grease into the supply line, and, for use, the reservoir being supplied with grease by the temporary removal of the feed plug 27, steam is admitted into the condensing chamber by opening the valve 13, whence the portion of the steam around the pipe 14 is condensed and the water of condensation flows downward in the water chamber M and by opening the valve 241 is admitted through the port 23 into the lower portion of the reservoir. At the same time, a portion of the steam flows downward through the pipe 1 1 into and through the heating pipe 7 and its nozzle 26 and is discharged into and along the feed pipe 17 and it is evident that when the water of condensation rises in the condensing chamber to the overflow pipe any excess will be discharged through this pipe into the feed pipe, the valve 18 being open, thus preventing any water of condensation from flowing into the steam pipe 14, and insuring that nothing but live steam will flow through this pipe into the heating pipe.

The flow of live steam through the heating pipe, and incidentally heat from the Wall of the water chamber, serves to heat the reservoir and reduce the grease therein to liquid form, and the same then flows through the feed port 22 and downward through the feed aperture 20, as controlled by the feed valve 21, and thence downward to the point of the valve whence it intermit- ,itently accumulates in drops which fall downward through the sight feed chamber, and are driven or drawn and sprayed by the steam from the nozzle of the heating pipe into and through the feed pipe and into the supply line.

The feed port 22, the valved feed aperture 20, the feed chamber 6 and the feed pipe 17, with the steam-discharge nipple 26, collectively constitute a feed-line in which the flow of liquid grease may be first detained to form globules, the formation and dropping of which may then be viewed in the sight feed chamber, after which the drops are impinged by the discharge from the steam nipple, and are driven through the feed pipe immediately into the supply line in a thoroughly heated and atomized condition.

For supplying lubricant at a point remote from the reservoir, one or more supplemental feed lines are provided, and each one preferably includes a case 5 forming a sight feed chamber 6 in the upper end of which is formed or secured the feed nipple 19 having the feed aperture 20 and the feed valve 21 with the communicating feed port 22*, and in the lower end of which is formed or secured the transverse feed-pipe 17 and a rease line leadin from the reservoir to the feed-port of the supplemental feed chamber is provided, and preferably includes the grease extension pipes 28 and 28*, with the intervening transversely disposed distributing drum 29 having the grease distributing chamber 30 in its upper side and the steam distributing chamber 31 in its lower side.

The grease extension pipe 28 leads from an opening at 32 in the upper portion of the reservoir downward into the upper side of the grease distributing chamber 30; and one or more grease extension pipes 28 lead downward from the lower side of the grease distributing chamber and the lower end of each one communicates with the grease port 22 of the supplemental feed chamber 6*; the upper end of the grease pipe 28 being preferably controlled by the valve 33, and the upper and lower ends of the grease pipe 28 being preferably controlled by the valves as 34 and 35.

The steam extension pipe 14? communisteam chamber 31, the lower end of which steam extension pipe 7 extends below the lower end of the grease pipe 28, and is connected in one end of the feed pipe 17*, and terminates in the discharge nozzle 26 directed in and along the feed pipe'17 across the lower opening of the supplemental feed chamber 6, the opening of which nozzle is preferably controlled by the valve 37. The other end of the feed pipe 17 is extended laterally and then preferably downward to a connection in and through the wall 38 of the engine cylinder or other steam line or chamber desired to be lubricated.

In the operation of the supplemental feed lines, the valve 33 controlling the opening of the upper'end of the grease pipe 28 being opened, it is evident that liquid grease from the upper portion of the reservoir will flow downward through this pipe into the grease chamber of the distributing drum, wherein it will be constantly heated by the steam in the steam chamber thereof, the valve 36 of the steam pipe 14 being open; and that by opening one of the valves 34 and the corresponding valves 35 and 37, the grease will flow downward through the corresponding grease extension pipe 28 in which it is kept constantly hot by the steam in the surrounding steam extension pipe 7*, and thence on into and through the supplemental feed line in the hot liquid form necessary for proper working, and is thereby fed into the engine cylinder in the usual manner, as into the steam line above described.

I claim:

A lubricator including a grease reservoir with means for heating the same, a remote feed-line having a chamber with a valved feed-aperture at one end and a feedpipe on one side and a steam-discharge nipple on the other side of the other end thereof, a steam pipe leading to the dischargenipple, and a grease pipe within the steam pipe leading from the reservoir to the feedaperture.
